Online transactional processing (OLTP) refers to the system of processes and technologies that are used to support and manage online transactions. These transactions can involve the exchange of goods or services, the transfer of money or other assets, or the processing of data or information.
OLTP systems are designed to handle a large volume of transactions in real-time, with a focus on speed, reliability, and security. They typically involve a database management system (DBMS) that stores and manages the data associated with the transactions, as well as a front-end interface that allows users to initiate and complete transactions.
OLTP systems are used in a wide range of industries and applications, including e-commerce, banking, healthcare, and government. In the e-commerce context, for example, an OLTP system might be used to process orders, payments, and shipments for an online store. In the banking industry, an OLTP system might be used to process account transactions, such as deposits, withdrawals, and transfers.
To support the high volume and real-time nature of online transactions, OLTP systems often use specialized database architectures and technologies, such as in-memory databases and high-speed storage systems. They may also use Load Balancing and other techniques to distribute the processing load across multiple servers or systems.
OLTP systems are typically designed to support the day-to-day operations of an organization or business, rather than long-term analysis or reporting. For these types of activities, organizations may use a separate system, such as an Online Analytical Processing (OLAP) system, which is designed for data analysis and reporting.
Overall, OLTP systems play a critical role in supporting and managing online transactions, ensuring that they are processed efficiently, securely, and reliably. They are used in a wide range of industries and applications to facilitate the exchange of goods, services, and information.
